Description

Videos integrated in Contao via the Youtube content element can only be viewed in full screen mode the first time after you have agreed to this in the overlay or inline blocker. After a reload or revisit of the page this is no longer possible (full screen is not available).

This happens because the iframe source can't be modified once the inner iframe detects it. The attributes within the iframe can't be detected due to another src.

Can you confirm that this change will work @drum-und-dran ?

You have to add this one line

if(parent.cookiebar.issetCookie(<?=$this->id?>)){
    const decoder = document.createElement('textarea');
    decoder.innerHTML = '<?=$this->redirect?>';
+   window.frameElement.src = '<?=$this->redirect?>';
    window.location.href = decoder.value;
}

(Yeah, the other window.location.href is needed as well, otherwise you'd see the "unblock" page and then it vanishes)

@drum-und-dran I hope you have some time to see if this solves your problem :) Feel free to open a pull request against the 1.x branch if it does ;)
